PORTABL PHoNoGRAPH.

Application mea March 3, 1924. seriarNo. 696,446.

To all whom it may concern: Be it known that I, SOLOMON SACHS, a

lcitizen of the United States of America, re-

phonograph of this character which makes use of the container as a soundbox, in other words, the portion or space which is occupied by thevarious parts of the phonograph in transportation may be used as anampliler when the phonograph is set yup for operation.

A'further object is to produce a tone arm which will close thecompartment' in the phonograph when the same is being carried.

Other objects are to provide a portable turn table, and tone arm, andreproducer, which can be carried inside the phonograph when the samejsnot in use.

Referring to the drawing wherein I have shown a preferred embodiment ofmy invention, Y

Fig. 1, is a top plan view of a portable phonograph made up to representthe conventional fiat pocket camera, the parts being shown dotted,

Fig. 2, is a view in side elevation, the

parts thereof being shown in section` of the phonograph in position foruse, the parts p thereof being v.shown inl their relative ,operatingposition, l Fig. 3, is a section on the line 3 3 of Fig. 2, and showsthe interior of the tone arm,

Fig. 4. is a top plan View of the motor4 endof the phonograph 'showing aturn table in open position thereon, the dot anddash lines showing theposition assumed by the arms of the turn table when the same are folded,i y

Fig. 5, is a View in perspective of a'modified form of mounting for thereproducer in this instance, the tone arm being dispensed with and aneXpandible supporting arm being used together with a slidable side pieceforthe phonograph, FFig. 6, is a section on the line 6-6 of Fig. `7, isa section on the line 7--7 of Fig. 5, Aand i Fig. 8, is a section on theline 8 8 of Fig. 5.

Referring to the drawing in detail, 5 indicates the housing for thephonograph parts which is so shaped as to simulate the pocket type .offiat camera having the rounded ends 6, and a carrying strap 7 In one endof the housing or container 5, there is fixed a suitable motor 8, theshaft 9 of which projects up through the top of the casing to receive aturn table 10, u on which may be mounted the usual recor 11.

The reproducer 12, is carried on the end of the tone arm13, through themedium of an inwardly extending flange 14, in said tone arm in which thetubular portion 15 of the reproducer frictionally lits.` The tone armhas formed in one end thereof, the vertical pipe 16, the lower end ofwhich is beaded as at 17 lto limit the. downward movement .of the pipein the casing opening 18.

This opening 18 leads into thev storage space for the parts and when theparts are in operating position, it can be seen that this space will actas an amplifying chamber for the sounds emitting from the tone arm 13,the end of the tone arm is suitably rounded to match the rounded end 6ofthe casing 5 so that when the same is placed in position against theloifset 19, in the motor housing, the same Will completely close theside of the phonograph and will retain in the sound box the reproducer12 and turn table 10.

.The tone arm is provided with suitable deectors 20, opposite theopenings therein so that the tone is conveyed directly' into the soundbox.

The turn table is composed f a suitable disk l21 having a fixed arm 22,and two pivoted arms 23, the latter of which when not in use may befolded down parallel to the arm 22 so that it can 'be seen that the turntable will occupy little space and may be stored in the sound box asshown in Fig. 1.

It is apparent also, that the loose connection of the pipe 16 in thecasing 5 permits4 of vertical movement of the reproducer 12, while thebead 17, permits of rotary movement of the vreproducer.

This combination tained,

provides Athe universal movement necessary to efficient operation of areproducer.

In F ig. 5, ll have shown a method of supporting the reproducer whichconsists in providing the housing 5 With a sliding side member 24:,which normally closes the side of the empty portion of the phonograph,in this instance, this unoccupied portion not being used as a sound box.At the end of this slide 24, ll provide a bracket 25 into which the endof a telescopic arm 26 is re-y thel forward end thereof being groovedannularly as at 27 and being adapted to fit into an extended tubeportion 28 of the reproducer 12,-this tube portion being provided withan opening 29 through Which passes a spring pressed pin 30, the pinengaging the groove 27 to hold the reproducer in position on the end ofthe arm. The reproducer carries, in this instance, the sound box oramplier which is made up of a hemispherica1 shell member 3l of celluloidor the like, having an extended neck 32 which fits into the usualopening or tube 15 of the reproducer. The amplifier is provided With anintegral preforated cover 33, having suitable openings 34; therein. Adisk member 35 is disposed beneath the cover 33 and is revolvably heldthereagainst through the' medium of a thumbv nut 36, this disk beingalso provided with openings to match the ones formed in the cover, sothat a revolving mbvement of the disk Will 'vary the volume of the soundemitted.

lln this construction, it is evident that the ampliier may be madeshallow enough to t into the housing and the supporting arm 26 may bealso telescoped so that it may be neoaoeo placed in the `housingtogether with the reproducer.

lln Fig. l, when the tone arm has been placed in the position shown toclose the opening of the casing, ll may provide suitable latch members37 to retain the same in this position.

llt Will be seen theretore, that ll have provided a portable phonographWhich can be carried in the pocket after the manner of the pocketcamera, and one which Willhave few parts, which may be quickly assembledand will operate efficiently.

Having described my invention, what ll claim is:

l. A' portable phonograph comprising a flat camera-like casing, a soundamplifying chamber in said casing having an open mouth, a tone arm forsaid phonograph, said tone arm when not 'in use being adapted to serveas a closure for the mouth of said chamber.

2. A portable phonograph comprising a casing having a portionconstituting a sound amplifying chamber terminating in an open mouth,said casing having an opening through one side thereof in communicationwith said sound amplifying chamber, and a tone arm communicating Withsaid chamber through said openingand adapted to serve When not in use asa closure for the mouth of said chamber.

lln testimony whereof ll hereunto adir my signature.
